2nd, it is communicatively connected to each other according to two converters of the bi-motor frequency-conversion drive apparatus of this utility model embodiment, often
The work state information of itself can be sent to other side by one converter, be caused corresponding when wherein one converter hinders for some reason
When motor cannot run, another converter can in time obtain the fault message of other side, and two-shipper mode of operation is changed to into list
Machine mode of operation, and after this converter for breaking down recovers normal, another converter also can in time obtain other side's recovery
Normal information, and again unit mode of operation is changed to into two-shipper mode of operation.
Description of the drawings
Fig. 1 is the theory diagram of the door machine bi-motor frequency-conversion drive apparatus according to the embodiment of this utility model one.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in detail with specific embodiment.
Refer to Fig. 1.According to the door machine bi-motor frequency-conversion drive apparatus of the embodiment of this utility model one, including the first frequency conversion
Device 11, the second converter 12 and for driving gate machine a pair of sliding doors the first motor 21 and the second motor 22；First motor
The outfan of 21 outfan and the second motor 22 is connected with each other by transmission belt 3.The transmission belt 3 for example can be belt or shoe
Band.
The first input end and the second input of the first converter 11 respectively with the output of the safety shoe switch 42 of door machine
The outfan of end and picking sensor 43 is electrically connected, the power input of the power output end of the first converter 11 and the first motor 21
End electrical connection.First converter also includes instructing and sending work to outside with closing the door from outside door open command for receiving
The input/output terminal of status information.During work, the input/output terminal of first converter 11 for example can connect with outside controller
Connect, with the door open command for receiving controller transmission and instruction of closing the door, and converter work state information is sent to into controller, on
Converter work state information is stated including output current, busbar voltage, output, current operation frequency, output torque etc..The
The input/output terminal of one converter 11 includes but is not limited to the modes such as terminal is connected, bus connects with the connected mode of controller.
The power output end of the second converter 12 is electrically connected with the power input of the second motor 22, and the second converter 22 and first becomes
Frequency device 12 is communicated to connect.It is preferred that the second converter 12 is communicated to connect by bus with the first converter 11.The shape of the bus
Formula includes but is not limited to CAN, MODBUS buses, DP buses etc..
During work, the first converter 11 is according to door open command, instruction of closing the door, the output signal of safety shoe switch 42 and light
The output signal of curtain sensor 43 carries out corresponding actions.First converter 11 passes through bus by dependent instruction and status information simultaneously
Send the second converter 12 to, the dependent instruction and work state information include four aspect contents, and one is order class data, including
Door open command, close the door instruction, velocity attitude, torque direction etc., two is that the output signal of safety shoe switch 42 and light curtain are passed
The output signal of sensor 43, three is converter work state information, including output current, busbar voltage, output, current fortune
Line frequency, output torque etc., four is door state information, including in enabling, in closing the door, open the door in place, door-closing in-place etc..Communication
When, the first converter 11 can as needed transmit the data needed for it.
Second converter 12 is set up with the first converter 11 and is shaken hands, and confirms that data receiver is correct, and the second converter 12 can be pressed
Relevant action is performed according to the instruction that the first converter 11 sends, communication failure, door machine bi-motor frequency-conversion drive apparatus are otherwise quoted
Proceed to unit operation pattern.
Second converter 12 can send itself work state information to first converter 11 in running, such as work as
Front running frequency, output current, busbar voltage, output, output torque etc..First converter 11 is by the first and second frequency conversions
The work state information unification of device sends the controller of outside to.If the first converter 11 breaks down, but it is unobstructed to communicate, then
While the first converter 11 is out of service, the second converter 12 proceeds to unit operation pattern.If the second 12, converter
Raw failure, but it is unobstructed to communicate, then while the second converter 12 is out of service, the first converter 11 proceeds to unit operation mould
Formula.After this converter for breaking down recovers normal, another converter also can in time obtain other side and recover normal letter
Breath, and again unit mode of operation is changed to into two-shipper mode of operation.
In another embodiment, the circuit structure of door machine bi-motor frequency-conversion drive apparatus and the basic phase of first embodiment
Together, its difference is that the second converter 12 includes instructing with closing the door from outside door open command for receiving and sending out to outside
Send the input/output terminal of converter work state information.During work, not only the input/output terminal of the first converter 11 with outside
Controller connects, and the input/output terminal of the second converter 12 is also connected with outside controller.Now, the second converter 12 is direct
The door open command and instruction of closing the door sent according to outside controller carries out corresponding action, the first converter 11 and the second frequency conversion
The work state information of itself is sent to respectively device 12 controller of outside.Even if when the first converter 11 occurs communication failure
When, the second converter 12 can also realize that unit works.
Aforesaid door machine can be elevator door-motor, and now, aforesaid sliding door is the car door of elevator, and aforesaid controller is
Electric life controller, but not limited to this.Aforesaid door machine can also be door machine of rail vehicle etc..
